SANITARY CONNECTION.

Specification of Letters Patent.

Patented Apr, 3, 1917.

To all whom it may concern:

Be it known that we, EDWARD H. LAW- RENCE and RAYMOND E. CRANE, citizens of the United States, residing at Cameron, Marshall county, West Virginia, and Chicago, Cook county, Illinois, respectively, have invented certain new and useful Improvements in Sanitary connections, of which the following is a specification.

Our invention relates to connection tubes principally used in connecting water closet tanks and bowls, and as explained in the following specification is constructed to provide a non-corrodible exposed tube and at the same time to eliminate the danger of breakage due to the settling of a building or to carelessness of the workmen in tightening the connecting nuts.

We attain these objects by the means shown in the following specification and illustrated in the accompanying drawing in which a vertical sectional view of the invention is shown.

The inside conduit A, is made of a flexible or malleable material to absorb shocks and strains. This inner conduit, A, is inserted in the hard sanitary outer shell, B, and afterward beaten or fitted to the contour of the inside of the shell, B, preferably with each end extended beyond the ends of the shell, B.

The drawing shows a bottle neck shaped end, made for the purpose of strengthening the shell at this point and for the further purpose of better holding the inner lining in place. It will be readily apparent to those skilled in the art that minor changes can be made in the construction without departing from the spirit of our invention.

What we claim therein as new and desire to secure by Letters Patent is 1. A. tubular connection for sanitary fixtures comprising a hard brittle, non-absorbent outer shell, a flexible inner conduit fitted to said outer shell and extending beyond the ends of said outer shell.

2. A tubular connection for sanitary fixtures comprising a hard brittle, non-absorbent outer shell, a flexible inner conduit, means for securing said inner conduit in place in'said outer shell.

3. A tubular connection for sanitary fixtures comprising a hard brittle, non-absorbent outer shell, a flexible water-tight inner conduit bent to conform to the inner shape of said outer shell, the ends of said inner conduit being arranged for direct connection with sanitary fixtures.

4. A tubular connection comprising a hard brittle, non-absorbent outer shell, a flexible water tight inner conduit formed to the inner contour of said outer shell, said outer A shell being made to a different inside diameter at a point near its ends, substantially as described.

In testimony whereof we aflix our signatures in the presence of two witnesses.

E. H. LAWRENCE. RAYMOND E. CRANE. Witnesses:

H. M. FISHER, IDA VAN CAMP.
